Description
技术领域
本发明属于植物基因工程领域,具体涉及茶树CsERF3基因及其应用。
背景技术
茶树(Camellia sinensis(L.)O.Kuntze)是我国重要的经济作物之一,也是我国重要的特色农业支柱产业。2017年我国茶叶的生产总量约达260.9万吨,出口量约为35.53万吨,均位居世界第一。茶树是典型的喜酸性土壤的农业经济作物,其最适土壤pH为4.5~5.5,在弱碱性乃至中性土壤中均难以生长或无法形成有效经济产量(骆耀平等,2008)。土壤盐渍化是影响作物产量及品质主要的因素之一,是世界性的生态问题和资源问题。全世界受盐害影响的土地面积大约共有11.25亿公顷,其中中东地区接近1.8亿公顷的土壤受到不同程度的盐害,而我国受盐害影响的土地面积超过1亿公顷,约占全国土地面积的11%(Hossain 2019)。近年来,土壤盐渍化愈演愈烈,盐胁迫对茶树生长发育造成的影响日趋严重,极大地制约了茶树产业的发展。因此,提高茶树品种的耐盐胁迫能力是目前茶树育种工作者面临的艰巨而亟待解决的重要任务。
目前,提高茶树耐盐胁迫能力主要通过传统的田间措施,如加强田间管理、改善栽培条件及人工补偿等,但由于逆境胁迫的不确定性常常导致防御应对不及时、不准确而造成严重的经济损失。因此,选育耐盐胁迫品种是解决茶树抗热问题的根本途径,然而茶树传统育种方法,如自然杂交、人工杂交、芽变选种和组织培养等,选育周期长且品种鉴定困难,使茶树遗传改良工作进展缓慢。随着生物技术的快速发展,基于细胞工程和转基因工程的分子育种技术日益成熟,已成为植物新品种选育的重要手段,其通过外源或内源基因的导入或沉默从而具有针对性地赋予或改善植物目标性状并保留原有的优良性状,这为茶树抗性育种工作提供了全新的思路和手段。
为了应对生物或者非生物胁迫,植物体经过长时间的进化形成了复杂的机制感知逆境信号。常见的激素如ABA、ETH、GA等作为信号分子参与调节植物生长发育、逆境调控等生物学过程(高春艳等,2017)。一些转录因子依赖激素介导的信号通路参与调控植物非生物胁迫响应,当然还有一些不依赖激素信号通路参与调控,分析转录因子的功能可以更好了解植物应对非生物胁迫的分子机制(Kavas et al 2015)。AP2/ERF是植物特有的转录因子家族之一,在植物应对低温、干旱、高盐等多种非生物胁迫方面发挥着重要作用(尤其是ERF亚族成员),能够参与多种激素信号通路影响植物逆境应答反应(Tao et al,2015)。因此,在茶树中发掘新的ERF类转录因子基因及其生物学特性和功能,可为整个植物抗逆基因调控网络及胁迫应答反应机理提供理论基础,并为改良植物抗逆性提供一定的物质基础。

结果发现CsERF3在在根、成熟叶和花中较低,在嫩叶和茎中有较高表达水平(图1A)。CsERF3在干旱(PEG)、高盐(NaCl)、低温和高温胁迫下的表达的总体趋势是上调,其中NaCl诱导CsERF3上调表达的速度明显快于干旱、低温和高温诱导(图1B)。
实施例3

使用的农杆菌菌株为EHA105。采用的是液氮冻融法将构建好的表达载体转入农杆菌。具体过程为:1)冰浴融化EHA105感受态细胞,加入至少100ng回收纯化的pCAMBIA1301-35s-CsERF3表达载体质粒,轻轻混匀,冰浴30min;2)液氮速冻5min,37℃水浴5min,迅速置于冰上1min;3)加入800μL无抗生素的YEB培养基,28℃,200rpm复苏2h;4)6000rpm离心2min,吸掉培养基;5)混匀剩余菌液,涂抹于添加50mg/ml卡纳霉素和50mg/ml利福平的固体YEB培基上;6)28℃倒置培养48-72h;7)PCR检测阳性克隆,得到EHA105:pCAMBIA1301-35s-CsERF3,4℃保存备用。
实施例5
CsERF3基因转化烟草,具体如下:
烟草种子用1%的次氯酸钠消毒后,在灭菌的三角瓶中用无菌水摇瓶培养,约2天后种皮破裂露出胚根。把萌发的烟草种子移到1/2MSB固体培养基上生长,培养条件为25℃、16h光照/8h黑暗的光周期。约一个月后,生长健壮的无菌苗即可切取叶片用作转化的外植体。
用农杆菌介导的叶盘转化法对烟草进行遗传转化。转化用农杆菌菌株接种于液体YEB培养基,28℃200rpm摇床培养过夜。将菌液吸取1mL接种于20-25mL的液体YEB中,28℃200rpm摇床培养作二次活化,菌液摇至OD600为0.6-0.8时,离心收集菌体,用等体积的液体YEB重悬备用。将无菌苗叶片切成约0.5cm×0.5cm大小,放入制备好的农杆菌菌液中侵染10min,倒去菌液,将外植体放在表面铺有一层滤纸的共培养基上,24℃暗培养2-3天。
共培养后,外植体接入筛选培养基中诱导分化,每2-3周继代一次。出现不定芽后,将生长健壮的不定芽切下,转入生根培养基中生根。当抗性苗生长健壮、根系发达的时候,洗净根部琼脂,炼苗2-3天后移栽到花钵中生长。
其中,
YEB培养基:0.5%蔗糖(W/V),1%细菌用胰化蛋白胨(W/V),0.1%细菌用酵母提取物(W/V),0.05%MgSO4·7H2O(W/V),pH 7.0。固体培养基灭菌前加入1.5%的琼脂粉(W/V);
MSB培养基:MS无机盐+B5有机+2.4g/L Gelrite+30g/L蔗糖,pH 5.8。
其中,MS无机盐采用下述记载的稀释倍数稀释MS无机母液后获得;
MS无机母液的配方(1000ml):
50×母液I:82.5g NH4NO3、95g KNO3、8.5g KH2PO4,
50×母液II:18.5g MgSO4·7H2O,
50×母液III:16.612g CaCl2,
50×母液IV:1.39g FeSO4·7H2O、1.866g Na2EDTA,
200×母液V:1.24g H3BO3、0.166g KI、0.05g Na2MoO4·2H2O、4.46g MnSO4·4H2O、3.3802gMnSO4·H2O、1.72g ZnSO4·7H2O、0.005g CuSO4·5H2O、0.005g CoCl2·6H2O。
B5有机:肌醇100mg/L+烟酸1mg/L+盐酸吡哆醇1mg/L。
烟草共培养培养基:1×MSB+0.5mg/L IAA+2mg/L 6-BA+30g/L蔗糖+2.4g/LGelrite,pH 5.4;
烟草筛选培养基:1×MSB+0.5mg/L IAA+2mg/L 6-BA+30g/L蔗糖+50mg/L Km+200mg/L CEF+2.4g/L Gelrite,pH5.8;
生根培养基:1×MSB+30g/L蔗糖+50mg/L Km+200mg/L CEF+2.4g/L Gelrite,pH5.8。
本实施例中,用根癌农杆菌介导的方式将CsERF3基因转入到烟草中,再生植株DNA使用CsERF3基因的特异性引物扩增。转CsERF3基因烟草的3个株系(L1、L2、L3)中均扩增出一条约594bp的特异性带,在野生型植株中未检测到相同的条带,表明CsERF3基因已成功整合到烟草基因组中。然后提取植株RNA,进行RT-PCR检测,结果显示CsERF3基因能够在烟草中正常表达,如图2所示。
实施例6:超量表达CsERF3提高耐高盐胁迫能力
将灭菌后的CsERF3过表达烟草株系(L2和L3)和野生型烟草种子放于分别添加含有0、100mmol/L和200mmol/L NaCl的1/2MS固体培养基上,在25℃,长日照(14h/10h,白天/黑夜)条件培养21天,做3个重复。结果显示,高盐处理L2和L3后,其存活率显著高于野生型(图3)。因此,在烟草中过表达CsERF3可以正向调控烟草对高盐胁迫的响应。
实施例7:超量表达CsERF3抑制烟草植株生长
与野生型烟草相比,超量表达CsERF3基因的转基因烟草株系L2和L3的植株高度明显降低,如图4所示。
以上所述的具体实施方式,对本发明的目的、技术方案和有益效果进行了进一步详细说明,所应理解的是,以上所述仅为本发明的具体实施方式而已,并不用于限定本发明的保护范围,凡在本发明的精神和原则之内,所做的任何修改、等同替换、改进等,均应包含在本发明的保护范围之内。
